As opposed to that, the indonesian-based Silat I've practiced (Indonesian Mande Muda and some bruneian silat suffian bela diri) has a focus on what it deems effective but the focus differs.

I made an error in this post. I meant to type out "Harimau", but I think I may have been watching a suffian bela diri video on youtube while typing this and it got into my head as I typed. Apologies all around!

I have also replied to this thread to showcase a couple of videos. the first is of Telesporo SubingSubing, a lesser-known martial artist in the FMA community. Mr. SubingSubing comes from Mindanao and some say that he taught a certain Mr. John Lacoste (who later settled in california and ended up teaching Mr Dan Inosanto) his style of fighting (The name of which has been lost and which many have dubbed simply as 'Moro-moro style'). I post this because I believe this is some of the very few footage we have access to in terms of Moro fighting systems:

It's said that Lacoste was a sailor in Mindanao when he met and trained under SubingSubing. I thought it was interesting enough to share with you gentlemen. Hopefully it will give us all more insight into how these blades were used.
